Strange Sounds

I know I'm generally a little paranoid... But did anyone else ever hear an odd sound at night that sounded like from within the home or the perimeter that completely thwarted any attempt to sleep afterwards? I heard what sounded like a tapping on the bedroom window (upstairs so rare chance someone was tapping it.) I carefully snooped around the windows of the house, wasn't gonna bother going outside. Saw nothing, that and well if someone really wants to get in one of the security systems will go off (the alarm system or the family German Shepard Jackie.) point is I've heard random noises over the years that completely ruined my chances of sleep. Wondering if these things bother anyone else?

I've always been a light sleeper (and strange noises in the night don't help!) but my dogs keep vigil over me when I do drift off. I really should work swing shift so I could sleep during the day :(

A couple of years ago I worked night shift 11pm-7am I was miserable for 7 months. I'd sleep from 8:30am then Just naturally wake up around 10:30-11:00am and never get to fall back asleep however hard I tried. Some people don't have the issue but a lot of guys I know had similar issues.

I lived in a 'haunted' house for 13 years with a so called 'noisy spirit'.

Try laying in bed and hear a large bookcase fall over (complete with the sounds of books and papers falling out onto the floor) followed by a horrendous crash that you can actually feel shake the house some early morning before dawn...

My one cat, sleeping on the corner of the bed, shot straight into the air during the the ruckus and landed looking terrified, fur standing on end.

And the kicker? Nothing amis in the room when I got up to asess the damage.

I have heard knocking three times while at work in a large newly built building in downtown Jacksonville, Fla. One was on glass. One was on a glass door. One was on wood right in front of me....Knock-Knock-Knock! Like someone wanting to come in.

A friend's Dad was getting ready for work one morning in the wee hours when a man's voice said clearly, "Well Hello Walter!" Without thinking my friend's Dad said "Hello" back, then realised it was only he, his wife and too young sons in the house with him.
His wife called from the bedroom asking who that was who had spoken as she and the two boys heard the voice too!
